WebIPTW is the inverse of the probability of receiving the treatment they received, given their own covariate history—for those who had L=0 and A=0, the IPTW would be 4/3, while for those who had L=0 and A=1, the IPTW will be 4/1. If, for ease of interpretation, we multiply each of these IPTWs by the relative ratio of the weights (3 to Webexposed to treatment t will be the same no matter what mechanism is used to assign treatment t to unit u and no matter what treatments the other units receive" (Rubin, 1986, p. 961).
